Ok, I don't really consider myself a moron, but Chemistry may turn me into one............. :-)
I understand what a shell is but can someone explain subshells, and orbitals without using analogies like rooms? I want to learn the correct terminology. For instance, is s, p, d, and f, the subshells or are they orbitals? A link to a website would be fine too. I can't find anything. Thanks.
I'll give 10 points to the first person who can help me understand it.

s,p,d and f are subshells. They contain orbitals.
s has one orbital which can contain 2 electrons.
p has 3 orbitals so 6 electrons total (2 electrons per orbital).
d has 5, so it can hold 10 electrons.
f has 7, so it can hold 14 electrons.
g has 9, so it can hold 18 electrons.

Hi. The shells are the first number, usually labelled "n". For each shell there is at least one subshell. In fact, for each shell of number "n" there are that many subshells. For example:
1: s
2: s, p
3. s,p,d
4. s,p,d,f
5. s,p,d,f,g
So these letters mean subshells. But each subshell has a number of orbitals.
s has 1 orbital, and a maximum of two electrons
p has 3 orbitals, and a maximum of 6 electrons
d has 5 orbitals, and a maximum of 10 electrons
f has 7 orbitals, and a maximum of 14 electrons
g has 9 orbitals, and a maximum of 18 electrons.
So, in order, shell-->subshell--->orbital--->
the final level is "spin", and for each orbital there can be two opposite spins, a positive and a negative.
If you look at the periodic table, the first row is the n=1, row 2 is n=2, etc. As you move across a row, you start filling in the orbitals of each subshell, starting with s (which has a max of 2). You always add to an orbital first before moving on to another orbital. When you add to a subshell like "p" you have three orbitals. You fill each of the three orbitals in order first (so that no one orbital has two electrons until all three orbitals are filled). For elements higher up, the ordering is a bit more tricky.

s, p, d, and f are orbitals. Each one has one or more subshells, depending on how many electrons the atom has.
To reiterate: orbitals have subshells. Subshells do not have orbitals.
Anyway, here's a decent article on wikipedia:

A subshell contains a number of orbitals and each orbital can hold two electrons in opposite spin, so that one electron is travelling in one direction, whilst the other travel in the opposite direction.
S-orbitals are spherical is shape and holds two electrons
P- orbitals are dumb -bell in shape and can hold six electrons (3 dumb bells, one in each plane of x, y and z axis)
d - orbital shape are difficult to describe but they can hold 10 electrons
f - orbital shape are even more difficult to describe but they can hold 14 electrons.
The orbital names (s, p, d, f _are derived from the quality of their spectroscopic lines: sharp, principal, diffuse and fundamental.
Hope that helps

think of roughly what you're sturdy at. There must be something you're sturdy or established at. do not hardship in case you're actually not specially sturdy at something, it particularly is okay in case you're established sturdy at it. i think of you're hooked on the internet (Or will replace into addicted interior the destiny ). that isn't probable something sturdy. you may discover ways to be extra constructive, in spite of ways "vivid" you're, and make extra friends (in genuine existence) who will take exhilaration in you for who you're. in spite of the reality that persons like that is uncommon to discover now, take it as a present which you will have the means to make friends who don't be your chum in basic terms for taking great ingredient approximately you. you are able to desire to discover ways to not be too gentle to others' feedback and once you won't be able to get closer others an analogous age as you, do not panic and alter into desperate. You pronounced a speech stutter, which would be why you have low-self-properly worth and picture down on your self an excellent style of the time. Ask your kin to help you triumph over the stutter. attempt to think of of ways a word will sound like on your head earlier asserting it out. it would help, i assume. From what you wrote, i think of which you do not in basic terms like the teachers/ instructions on account which you do not understand them? maybe next time you are able to attempt and jot down notes for the duration of classification, particularly those you do not understand / understand so which you would be able to ask human beings or the instructor after classification. it particularly is frequently sturdy to envision previous to each financial disaster so as which you already know what the instructor is speaking approximately. i'm hoping this helped, sorry if I went off topic :)
